Artists changed their avatar to cyan blue over the weekend to match the color of the company logo of Tidal, Jay Z's new music streaming service, which is expected to launch Monday.

Jay Z reportedly first began lining up the support of his celebrity pals before this year's Grammy's.

He hosted a meeting in Los Angeles before last month's Grammy Awards to discuss his purchase, which was reportedly attended by Kanye West, Rihanna, Madonna, Coldplay's Chris Martin, Jack White, Daft Punk, Nicki Minaj, and Beyoncé, according to Showbiz 411.

At the meeting the artists discussed ways to profit from distributing their own work and focused on "videos, artists' rights and how music has been diminished by crass commercialism."

On Sunday night, many of those artists who attended the meeting with Jay Z tweeted their support and changed their avatars to match Tidal’s cyan blue logo.
